'HAMILTON LINDSAY, OF CLEVELAND, OI-IIO, ASSIGNOR TO THE LINDSAY WIRE WEAVING COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

SHUTTLE.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed March 15,1906. Serial No. 306,147.

Be it known that I, HAMILTON LINDSAY, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Shuttlcs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to shuttles for looirs. It is well adapted for looms used in weaving wire-cloth and may be employed in other loonis.

The object of the invention is to form eflicient means for tightly holding the spindle in the shuttle and allowing its convenient removal and replacement when desired.

The particular characteristics of the invention are hereinai ter more fully explained, and definitely set out in the claims.

In the drawings, Figure 1 is a plan of a shuttle embodying my invention. Fig. 2 is a bottom view thereof. Fig. 3 is a vertical longitudinal section substantially on the ofl'set line 3 3 of Fig. 1. Figs. 4, 5, and 6 are cross sections on the correspondinglynumbered lines of Fig. 1.

Referring to the embodiment shown in the drawings, the frame of the shuttle consists of the two sides A A, brought together at the ends, and the two cross-balsa a. There may also be a bottom brace-plate (0*. Between the cross-bars and the points of the shuttle are mounted rollers B. On the inner side of the cross-plate a is formed a recess or pocket to receive the head of the spindle and hold it in place. This pocket is made by a pair of lugs a a, extending inward from the side members of the llttl'lll. The faces of these lugs near the proximate end of the shuttle are beveled downwardly toward such end, as shown in Fig. 3. The sides A A are also beveled inwardly toward the base of the shuttle at this point, as shown in Fig. 5. i

E represents the spindle, adapted to have wire-thread F or other material wound on its surface. T lie spindle lies a tubular bore a of use in the winning-machine, and the exterior is tapered outwardly from the free end.

to a circular boss 6, which extends to and I'OIDTS an integral part of the quadrangular head 6 which is tapered on its front side and along its ends to correspond with the taper of the lugs a a and the sides A A. By this means the head is made to fit snugly in the pocket of the frame. The boss e may be cut out alittle at e to allow its passage across the lug a.

T 0 hold the spindle firmly in place, I provide a locking-pin D, mounted in the frameplate a and pressed toward the pocket bya spring D, riveted at its lower end to the frame member. The upper end of this spring is turned over, as shown at (1, allowing the thumb-nail to be inserted between it and theplate a to withdraw the pin. The spindle may thus be removed whenever desired. To insert it, it is simply placed with its head over the pocket and the head shoved into place, the bevel thereo'l allowing it to pass over the end of the pin D and gradually force the same backward until it springs home as the spindle comes into place. The thread from the spindle passes out under the roller 0 and over the roller 0, mounted on a bracket C, secured to the 'l'ranie-plate a.

It is desirable to provide friction means to prevent the material being pulled off the spindle too freely. The means shown in the drawings are the subject of my divisional ap plication, Serial No. 328,306, filed July 30, 1906, and are there claimed. Briefly, they consist of a flexible metallic friction nieniber G, which maybe a loop of piano-wire the ends of which are carried by a pair of rubber straps G, which are held by screws onthe inner faces of the sides A and A in such position that the wire passes diagonally acrcss the spindle and bears against the material thereon. Elasticity of the straps maintains the proper tension.

I claim- 1. The combination with a shuttle-body having a tapered recess with lateral extensions, of a spindle having a tapered T-head adapted to seat in such recess, and means for holding the same therein.

2. A shuttle-body having a tapered recess, a spindle having a tapered head adapted to seat in such recess, a pin adapted to lock the spindle in the shuttle, and a spring acting on such pin.

3. A shuttle-body having a recess, a spindle having a head adapted to seat in such recess, a pin carried by the shuttle-body adapted to engage such head when properly positioned in the recess, and a spring tending to force the pin toward the head.

4. In a shuttle, the combination of a cross member, a pin mounted therein, a spindle having a head adapted to bear aganist the cross member, and meansv for holding the,

1spindle with its head against the. cross mem- 5. The combination of a shuttle-body having a pair of side members and a cross member, lugs extending inwardly from the side members in advance of the cross member to make an open recess, and a spindle having a head adapted to occupy said recess, the spiniile extending from the head between said ugs.

6. The combination of a shuttle-body having near one end a cross-recess opening toward the center of the shuttlebody, a sp ndle having a head adapted to occupy said recess, the spindle-shank extending out of the recess. and a pin carried by the frame and adapted to engage the spindle when its. head is properly positioned in the recess.

7. The combination of a shuttle having a pair of side members and lugs extending inwardly from the side members to make a recess between them and the end of the shuttle, a spindle having a head adapted to occupy said recess, the spindle extending from the head between said lu s, and the recess and the head being tapered to. cause the head to .fit snugly in the recess.

8. A shuttle having a pair of side members and a. cross member, lugs extending inwardly to the side members in advance of the cross member to leave an open pocket between shuttle, the flare of the, taper extending 'toward the top of the shuttle, combined with a spindle having a quadrangular head adapted to occupy such pocket with its ends engaging the sides of the shuttle and its face engaging such lugs, the shank of the spindle being adapted to extend between the lugs.

9. The combination of a shuttle-body having a cross-recess with a contracted opening and a spindle having a head adapted to occupy said recess, the shank of thespindle extending through such opening, said head and recess bein correspondingly tapered.

10. The combination of a shuttle body having a cross-recess with a contracted opening and a spindle having a head adapted to occupy said recess, the shank of the spindle extending through such opening, and means for locking said head in said recess.

11. The combination with a shuttle-body having side bars and a tapered recess provided by a cross-bar and lugs projecting inwardly from the side bars respectively, of a spindle having a tapered head adapted to seat in such recess, and means for holding the same therein.

In testimony whereof I hereunto ail ix my signature in the, presence of two witnesses.

HAMILTON LINDSAY.
